Jessica Simpson's Tony support

Jessica Simpson has vowed to continue supporting her American football star boyfriend, despite being branded a "jinx".

The singer is not worried by reports that Tony Romo's teammates believe she is bad luck, and won't let it stop her attending his matches.

She said: "That jinx story was absolutely ridiculous. I won't be wearing my jersey to games anymore, but I have been there and definitely going to support the Dallas Cowboys all the way."

Jessica - who will soon release her debut country album 'Do You Know' - also revealed her reasons for her new musical direction.

She added to US TV show 'Extra': "Country was just something that's in my bones. It's in my blood. It's in my voice. It's in my heart and I just wanted to pack my stuff up and go to Nashville and write with some of my favourite songwriters."
